We had some user accuracy parts made (Jacobs, Rapid Prototyping and 
Manufacturing, (1992), p.308.) by Sanders last Fall.  The parts were waxy and 
brittle - stronger than wax patterns but more fragile than the old acrylate SLA 
resins.  Dimensional analysis summary follows:

Dimension (in)   Error (%)
0.0525           13.0%
0.125             3.6%
0.35              1.2%
0.5               1.0%
1.0               0.5%
1.5 - 2.5         0.4%

Sanders phone# is (603) 654-6100.  I believe that they have been focusing on 
software upgrades to enhance build speed.
